Tri-Planar Vll "SE Upgrade"

Have made a improvement to this otherwise excellent tonearm.  I found the VTA/SRA adjustment "tower" did not hold the arm base firmly enough with its single knurled screw attachment especially if one is more than half way up on this adjustment.  If your constantly fiddling with VTA/SRA its probably not a benefit, but I don't, so I designed a add on tri-point stabilizing ring for this, see virtual systems page for how it works. Last picture. This adds tremendous stability to the tonearms mounting rigidity.

We can make more should anyone have an interest. Since it a specialized item and probably only to be made in a very small quantity it will not be inexpensive though. 


Good Listning,

Peter,

That sounds like a good idea.  Stability is always important.  I noticed your Triplanar still has the damping trough.  If you are not actually using the trough, you should try removing it from the arm.  I did that a number of years ago and was surprised by the improvement in sound quality.  It was too long ago for me to recall the specifics but it was an easily noticeable improvement. 

Salectric,

Thanks for the suggestion - but the U12 has the armrest mounted to the damper through, were the earlier versions different ?


Good Listening

Peter

Yes, the damping trough was removable on the VII without affecting the armrest.  I didn't realize that had changed.

Hello All,
Thank you Peter at PBN Audio for confirming our measurement.
